Tell user what to do if there's no more space on backup location

[Branimir Kolar]

So today my backup destination got out of space and backup failed and informed me about that.

And that's it. If I'm a new user I would be perplexed about what to do next.

And all I have to do is to change 'keep backups' option to a smaller time span or maybe only restart backups (if it does delete old backups on low space automatically - I didn't try that). So I think deja dup could just suggest that to me on that same error window I got when backup failed.

Strictly speaking this is backup preventing (and still a problem in recent versions of the software).

There's another problem here. Deja Dup says it will delete older backups when it runs out of space. I'm 100% sure it does not do so. I had a virtual server with 20 GB of disk space dedicated solely to Deja Dup backups, but Deja Dup failed to make any further backups (and failed to present any reasonable error message) due to running out of space. It should have just deleted old backups, like it claimed it would.

+1, Deja dup should delete old backups. It says that it will when set to keep backups at least size months, but doesn't at all. It keeps filling up the backup drives and never deletes old backups.
